the perfect handhold tester series
optical variable attenuator tw3303
tw3303 handhold optical variable attenuator is used for continuously
variable optical signal attenuation. As the attenuator is used in the
laser system for the on-line testing, there, thereforetw3303 can be
used in the digital system of communication devices (such as: phd,
sdh) and also in the system of adopting analog modulation (catv)
application
ø telecom maintenance
ø catv maintenance
ø comprehensive cable construction system
ø optical instruments research and development
ø optical communication education and lab testing
ø other optical project
features
ø stepwise attenuating by circumgyrated dial: attenuating
step 0.05db
ø provide with the function of displaying db and dbm
attenuating value
ø alternative function of 10 minutes auto-off without
operation
ø after off the instruments, the system will have the
memorizing of the attenuating value and the attenuating step, in
order to restore the system back to the previous shut down state when
open the instruments next time.
